For Magnetic Resonance Imaging (MRI) applications, it can be important to collect auxiliary physiological data in conjunction with the Nuclear Magnetic Resonance (NMR) image data. This auxiliary data includes physiological signals such as: Electrocardiogram (ECG), Electromyogram (EMG), Electroculogram (EOG), Electrogastrogram (EGG), Temperature, Respiration, Eccrine Activity (EDA, EDR, SCL, SCR or GSR), Blood Volume Pulse (PPG), Hand Grip Strength (Dynamometry), Finger Twitch, and a variety of pressure based signals.
This application note addresses some of the practical concerns associated with collecting physiological data during the MRI scanning process. Practical concerns relate to the ability to collect such data while maintaining:
A safe environment for the subject.
High quality NMR image data.
IMPORTANT!See Safety Guidelinesfor recording biopotential measurements in the MRI environment.
The NIBP100E noninvasive blood pressure system provides continuous, beat‐to‐beat, blood pressure signal and values (Sys, Dia, MAP) and Pulse Rate (PR)*. The NIBP100E amplifier with CNAP™ technology is controlled by AcqKnowledge software (v5.0.7) for MP160 Research Systems. The system outputs a continuous blood pressure waveform that is similar to a direct arterial pressure waveform. The amplifier […]
BIOPAC provides software and hardware that allows research teams to study physiological measures related to stress. Here are a few notable studies using BIOPAC equipment for ECG, EDA, and EEG/ERP. Moms Moderating Stress Can relaxation techniques help lower stress on both mother and fetus? Using an MP36R Data Acquisition system to record ECG and EDA, this study […]
